Industrial fans are commonly used in factory ventilation and cooling equipment and are widely used in high spaces such as industrial factories, logistics warehousing, waiting rooms, exhibition halls, gymnasiums, and supermarkets.  Industrial large fans can push a large amount of airflow to the ground, forming a horizontal movement of airflow layer at a certain height on the ground, thereby promoting overall air circulation.  Its advantages are ground coverage and three-dimensional circulation of air.  Large industrial fans can reach 7.2 meters in diameter!  The streamlined fan blade is manufactured using aerodynamic principles and advanced technology. It only needs 1.3KW to drive a large amount of air, generate a large-area natural breeze system, and play the dual role of ventilation and cooling.  Compared with traditional HVAC and small high-speed fans, it has unparalleled application advantages and can be called a solution for high-altitude ventilation and cooling.             Dezhou Linghao Refrigeration Equipment Co., Ltd., since its establishment, has always been technology-oriented, and has risen rapidly in the field of ventilation and air conditioning equipment.
